inTEST Receives Largest Order in Company’s History for Optical Transceiver Production Test

MOUNT LAUREL, NJ, December 13, 2017 - inTEST Corporation (NYSE American: INTT), an independent designer, manufacturer and marketer of thermal management products and semiconductor automatic test equipment (ATE) interface solutions, announced today that the Company recently won an order for 112 temperature forcing systems valued at over $2.6 million and comprised of several different models, from two Asian-based existing customers. The order, which is expected to ship before the end of fiscal year 2017, was won by the Company’s thermal unit, inTEST Thermal Solutions (iTS), a provider of thermal systems for electronic test and the world’s leading supplier of temperature systems for use in optical transceiver characterization and testing.

inTEST Executive Vice President and Chief Operating Officer, James Pelrin, commented, “This order is confirmation of the strength and breadth of inTEST’s thermal solutions temperature systems portfolio. One of the customers placed the largest order ever received by inTEST for our ThermoStream® systems from a single customer. Leading manufacturers of optical transceivers use ThermoStream to provide rapid temperature transitions with very precise temperature control.

“Worldwide demand for increased data bandwidth is driving the need for faster communications in smaller packages. Transceivers use lasers whose frequency is affected by temperature and require calibration at various temperature points at the end of their production cycle where ThermoStream systems are used.” Pelrin concluded, “This was a competitive bid, with the win attributable to the systems’ record of long-term reliable performance, iTS’ ability to meet an aggressive delivery schedule, and well-established customer support.”

About ThermoStream® Systems

ThermoStreams® are portable systems that deliver clean dry air for precision temperature testing or conditioning of electronics (ICs, MEMS, transceivers, or circuits) and materials. These systems provide precise temperature control with very fast transitions to reach each temperature, aiding lab and production test efficiency. The ThermoStream achieves this by creating a stable environment in seconds. Using Device-Under-Test (DUT) control, the ThermoStream can temperature cycle a device from ambient to -20◦C in under 10 seconds. With rapid thermal cycling or long saturation at a precise temperature, these systems optimize throughput for characterization, verification, thermal shock or failure analysis applications – at the test bench or on the production floor.
